Which of the following types of material interacts most strongly with radio waves?
The more strongly electromagnetic radiation interacts with living tissues, the more damage it can do to those tissues. Further inside the body of organisms are more vital organs and tissues, damage to which is more harmful to organisms. The strength of interaction with human body tissues and the depth of penetration into the human body of different types of electromagnetic radiation is shown in the diagram.
What is the most dangerous type of electromagnetic radiation to humans?
Which is more dangerous to humans, microwave radiation or infrared radiation?
Are radio waves more dangerous or less dangerous to humans than infrared waves?
One or more of the following types of electromagnetic radiation contain no wavelengths that are ionising but are still able to damage living tissues. Which of these types can damage living tissue in ways that do not require ionisation to occur?
